GAS VALVE.

Application filed October 16, 1914.

To all whom z't may concern:

Be it known that I, MAXYMILIAN J. MYSZ- nan, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Ii'nproveinents in Gas-Valves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to gas valves and has for its object the production of a simple and e'licient means for sounding an .alarm when the gas pressure is reduced.

Another object of this invention is the production oi a simple and eilicient actuating means for sounding the alarm after the pressure of the gas falls to a certain point.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings Figure l is a side elevation of the device showing the electrical wiring connection in diagram.

Fig. 2 is an end view partly broken away showing` the valve casing.

Fig. 3 is a section taken on line 3-3, of Fig. 1.

Fig. 4 is a vertical transverse section through the casing adapted to contain the main supply valve, showing the actuating means carried thereby.

Fig. 5 is a section taken at right angles to Fig. 4- through the main supply valve casing.

Fig. 6 is a vertical section taken on line 6 6, of Fig. 1.

Fig. 7 is a perspective view of the circuit closing mechanism carried by the valve casing.

Fig. 8 is a section taken on line 8 8, of Fig. 2.

Fig. 9 is a perspective view. of the circuit closing' member adapted to be actuated by the gas control valve.

Fig. 10 is a perspective view of the indieating hand used in connection with the main supply valve.

Fig. 11 is a section taken on line 11-11, of Fig. l.

By referring to the drawinfrs it will be seen that 1 designates the main supply valve casing through which passes the main supf ply pipe 2 having a rotating valve 3 placed Specification of Letters Patent.

therein, which valve 3 operated by a valve operating stem t.

A spring' carrying shaft 5 is connected to the valve stem 4- and carries a coil spring 6 and also a ratchet wheel 7, which ratchet wheel is normally held in a set position by the pawl S carried by the shaft 8. The armature arm 9 is engaged by the armature 9 when this armature 9 is drawn into engagement with the electro-magnets 9 when these magnets are energized by the closing of a circuitV to be hereinafter set forth. lvhen the armature arm is swung by the armature 9 the shaft 8 will pivot so as to swingr the pawl 8 trom engagement with the ratchet wheel 7, thus allowing the shaft to be rotated by the spring for cutting off the How of gas through the valve 30, as clearly disclosed in my prior application, iiled October 16, 1913, Serial Number 795,607.

The shaft 5, however, carries an indicating hand 10 which may be removed therefrom when it is desired to wind the spring 6, and a detachable thumb nut 11 is mounted upon the shaft 5 for the purpose of facilitating the rotation of the shaft 5.

A contact bracket 12 is supported upon the main valve casing l and is insulated therefrom, and this bracket 12 is provided with a projecting finger 13. which finger is adapted to be engaged by the indicating hand 10 when said hand is swungvand makes contact therewith. The operation of the indicating hand 10 will be more clearly hereinafter described.

The gas supply pipe 2 supports an automatic valve containing casingv comprising a metal base 14 upon which is supported the glass cylinder 1.5. 'A metal cover 16 is supported upon the glass cylinder 15 and constitutes a closure Jfor the upper end thereof. A connection post supporting bar 17 is connected to the metal base of the casing 1,4- and carries a contact post 18 to which is connected the top 16. This top 16 is also connected to the electro-magnetic means 9 by means of the wire 19 for actuating the same in conjunction with the mechanism to be hereinafter described.

The gas supply pipe 2 is provided with an upwardly extending portion 20 in which is formed a discharge aperture 21. A slidably mounted cap 22 is mounted in the upper end of the pipe 2O and is also provided with an aperture 23 which is adapted to register with the aperture 21 to allow the gas to escape into the casing and then pass out through the pipe 25 to the burner 24E.

The cap 22 is provided with an outvardly projecting arm 26 having an off-set end 27, which oset end travels in a longitudinally slotted member 28 as is clearly illustrated in Fig. 2. rlhis longitudinally extending slotted member 23 is carried by a shaft 29, which shaft is journaled in a bearing 30 carried by the cover 1G of the cylinder 15. rl contact plate 31 is carried by the shaft 29 as the cap 22 moves downwardly to the position shown in dotted lines in Fig. 2, the apertures 21 and 23 will move out of registration and prevent the passage of gas therethrough, and this downward movement of the cap will swing the contact member 31 to the position shown in dotted lines after first having caused the contact member 31 to form an electrical contact with the pivoted contact flap 32. A supporting post 33 is carried upon a supporting plate 3d, and this supporting post 33 carries a bracket having a binding pos 36 to which the yire 37 1s connected. The

bracket is provided with an upwardly extending portion 38, The bracket Ll1 is mounted upon the bracket 33, as shown in Fig. 8, and the screw 40 formed upon the bracket t1 supports a hanger bracket 39. The screw -lO carries a sleeve l2 upon which is supported a depending contact wire 43 which is adapted to be engaged by the olfset arm lll of the crank 45, which crank supports the contact flap 32 above described. rlhe wire 37 is also connected to the batteries which are in turn connected to the electromagnetic operating means for actuating the valve 3 by means of the wire 54.

A bell circuit is also employed in connection with the present electrical mechanism which comprises a wire connected to the wire 37 which is connected to the battery 50. The wire 55 is connected to a bell or other suitable signal 56, and this bell is connected to the bracket 12 by means of a wire 57. The operation of the present device is as follows:

When the gas is at its normal pressure the cap will be heldin the position shown in Fig. 1, thereby allowing the apertures 21 and 23 toregister. After the pressure of the gas, however, falls below the pre-deter mined point, the cap 22 will drop and close the passage-way between the apertures 21 and 23, and cause, at the same time, the plate 31 to swing to the position shown iu dotted lines caused by the cd1-set arm 27 traveling in the' longitudinally extending slotted member 23.

As the contact member 31 comes in contact withthe flap 32, the electric current will pass from the battery 50 through the Leichen wire 37, through the bracket 33, through the depending wire e3, through the crank 45, through the heap 32, through the contact plate 31, through the top of the casing 16, through the wire 19, through the magnetiy operating means 9, through the wire 54, and then through the battery 50, there by actuating the magnetic means 9 for operating' the valve carried by the pipe 2.

it should be uncerstood that simultaneous with the operation of the circuit just described a current will pass from the battery 50 through the wire' 55, through the bell 56, through the wire 57, to the contact point 13, through the arrow 10, through the wire 10A to the wire and then to the battery 50.

From the foregoing description it will be seen that a very simple and ethcient means has been produced for automatically cutting off the flow of gas to prevent the accidentalescape of the gas after the light has been extinguished due to the falling of the pressure of the gas supply.

Having thus described the invention. what is claimed as new, is
